Use of Internal Hard Disk Drives in the RAID System
This section describes how to use the hard disk drives installed in the HDD cage at the front of the server in the
RAID System.
Important
•
If you use hard disk drives in the RAID System or change the RAID level,
initialize the hard disk drives. If the hard disk drive contains valuable
data, be sure to backup the hard disk drive before installing the RAID
Controller and configuring the RAID System.
•
Do not change the mode to hibernate when building a RAID System.
Note
In the RAID System, use hard disk drives that have the same specifications
(capacity, rotational speed, and standard) for each Disk Array.
Tips
•
Logical Drives can be created even with only one Physical Device.
•
Understand the characteristics of each RAID Controller such as available RAID
levels or hard disk drives and choose an appropriate RAID Controller.
•
Logical Drives except for RAID0 have a smaller usable capacity compared to the
total capacity of the hard disk drive in the Logical Drive, while disk reliability
increases.
You can set up a RAID system by using the on-board RAID controller (LSI Embedded MegaRAID™).
To use this RAID system, it is necessary to install two hard disk drives on the server. For details on the
procedure of installing hard disk drives, refer to
Chapter 2 (1.7 Hard Disk Drive (HDD) / Solid State Drive (SSD))
in this manual.
1.8.1
Enabling a RAID System
You can use the installed hard disk drives as single hard disk drives or as a RAID system.
To set up the installed hard disk drives as a RAID system, select
Advanced
,
PCI Configuration
, and
Onboard
SCSI
from the
BIOS Setup
menu, and then set
Option ROM Scan
to
Enabled
. (For details, refer to
Chapter 2
(1. System BIOS)
in the
“Maintenance Guide”
.)
Tips
The hard disk drives are set to be used as a RAID system as the factory default.
